Getting started đŸŽ¯

There are multiple commands integrated into jenesis that allow you to perform a variety of tasks. A full list of these commands is provided below:

  • new
  • init
  • add
  • update
  • attach
  • compile
  • keys
  • deploy
  • run
  • shell
  • network

In the following section of this page, we will cover the first commands so to show you how to create a new project and how to configure a network.

For additional information, have a look at the Keys ↗ī¸ documentation for information about managing keys using Jenesis and the Working with contracts section, which illustrates different contract related executable operations using Jenesis tools and commands.

Let's get started!

Create a new project

You can create a new project using the new command as depicted below:

jenesis new my_project [--profile my_profile] [--network network_name]

This will create a new directory called my_project. You can use --profile and --network optional arguments to provide additional arguments for profile and network desired for the project. Whenever these arguments are not used, these will be set to testing and fetchai-testnet respectively.

Inside this directory for your project, a jenesis.toml file will be created containing the following information:

[project]
name = "my_project"
authors = [ "Alice Tyler <[email protected]>"]
keyring_backend = "os"
 
[profile.my_profile]
default = true
 
[profile.my_profile.network]
name = "fetchai-testnet"
chain_id = "dorado-1"
fee_minimum_gas_price = 5000000000
fee_denomination = "atestfet"
staking_denomination = "atestfet"
url = "grpc+https://grpc-dorado.fetch.ai"
faucet_url = "https://faucet-dorado.fetch.ai"
is_local = false
 
[profile.my_profile.contracts]

The project's name is the argument passed to the new command while the authors field is populated by querying the user's GitHub username and email address. The profile's network will be filled with the relevant configuration variables. The contracts field will remain empty until new contracts are added. This my_profile profile will be set as the default profile, this means that every time you use a jenesis command without specifying a profile, my_profile will be used.

An empty contracts folder will also be created inside my_project directory that will eventually contain all the information needed to compile and deploy the desired contracts.

The init command is similar to the new`` command, but in this case, you will not need a project name` argument since this command is intended to run inside an existing project directory:

jenesis init [--profile my_profile] [--network network_name]

This command will create the same files and folders inside your project directory as the ones described for the new command above.

If using a cargo workspace, you just need to navigate to the top level of your project and run the init command shown above. This will create the jenesis.toml configuration file inside your workspace including all the relevant information from existing contracts.

Configure a network

Jenesis will configure the project to run on the latest stable Fetch.ai testnet by default,. Use fetchai-mainnet to configure for the Fetch.ai mainnet or directly edit the jenesis.toml file to configure for other networks.

If you want to test on a local node, you will need to pass the argument --network fetchai-localnode when creating a project:

jenesis new my_project --network fetchai-localnode

or:

jenesis init --network fetchai-localnode

The configuration can be found under the network heading in the jenesis.toml file and can be changed as desired:

[profile.testing.network]
name = "fetchai-localnode"
chain_id = "localnode"
fee_minimum_gas_price = 5000000000
fee_denomination = "atestfet"
staking_denomination = "atestfet"
url = "grpc+http://127.0.0.1:9090/"
is_local = true
keep_running = false
cli_binary = "fetchd"
validator_key_name = "validator"
mnemonic = "gap bomb bulk border original scare assault pelican resemble found laptop skin gesture height inflict clinic reject giggle hurdle bubble soldier hurt moon hint"
password = "12345678"
moniker = "test-node"
genesis_accounts = [ "fetch1vas6cc9650z0s08230ytqjphgzl5tcq9crqhhu",]
timeout_commit = "5s"
debug_trace = true

In particular, to fund some accounts for testing, replace the genesis_accounts field with the addresses to be funded.

When running any of the commands deploy, run, shell, and attach, Jenesis will check for a currently running local node. If there is not one provided, a new one will be created in a docker container.

If you wish to keep a local node running, you need to set the keep_running parameter to true. Otherwise, nodes will be stopped after any of the command mentioned above finish running.

At any time, you can start or stop a local node from running, using the following commands:

jenesis network start [--profile my_profile]

or:

jenesis network stop [--profile my_profile]

You can also view the logs from the local node, by simply running:

jenesis network logs [--profile my_profile]
